You need a non stick sheet to make the crisps or I find that it doesn't work. Mix your soup into a thick paste, and then spread a teaspoon full thinly onto the sheet. Put in the microwave for about a minute, keep checking so it doesn't burn. If it is done, it will peel off the sheet, if not, bung it back in for a few more seconds. Peel off the sheet and leave it to crisp up, and voila!!
Yummy yum.
Let me know how you get on!
